Explaining broad molecular, phenotypic and species biodiversity patterns necessitates a
unifying framework spanning multiple evolutionary scales. Here we argue that although …

Studies of speciation typically investigate the evolution of reproductive isolation between
populations, but several other processes can serve as key steps limiting the formation of …

Humans have been driving a global erosion of species richness for millennia, but the
consequences of past extinctions for other dimensions of biodiversity—functional and …

Large Amazonian rivers impede dispersal for many species, but lowland river networks
frequently rearrange, thereby altering the location and effectiveness of river barriers through …

Evaluating the factors that drive patterns of population differentiation in plants is critical for
understanding several biological processes such as local adaptation and incipient …

Rates of species formation vary widely across the tree of life and contribute to massive
disparities in species richness among clades. This variation can emerge from differences in …

Insectivorous birds reach their highest diversity in the tropics and represent a striking variety
of morphological and behavioral specializations for foraging, yet explanations for these …

Dispersal ability is known to influence geographical structuring of genetic variation within
species, with a direct relationship between low vagility and population genetic structure …

Many quantitative traits, for example body size, have been hypothesized to influence the
diversification dynamics of lineages over macroevolutionary time‐scales. The Quantitative …

The ecological traits of organisms may predict their genetic diversity and population genetic
structure and mediate the action of evolutionary processes important for speciation and …
